Consider this family of octal tri-state buffer chips: 74240, 74241, and 74244. com Port 80. Also, a thiz delay (to indicate a driver turn off time ) is used in addition to the rise and fall delay times. This could be built from single quad 2-input NAND gate such as a SN74LS00 or CD4011. I was figuring some sort of tri-state buffer, so that it can output vcc,gnd and still pass on any digital reading in a z state does anyone know of any simple ics that do this? A quick search wasn't fruitful for me I was thinking op amps at first but idk how I would make that into a zstate. Only one device can talk at a time; the others are disabled.
